The ratio of the male to female employees in the company
in 2015 was 5:4, respectively. In 2016, the male employees and female employees increased by 18% and 20%, respectively. If the total number of employees in 2016 was 3852, then find the number of female employees in 2015.Solution
Let the number of male and female employees in 2015 be 5x and 4x, respectively.
According to question,
1.18 × 5x + 1.2 × 4x = 3852
5.9x + 4.8x = 3852
10.7x = 3852, x = 360
So, required number of female employees = 4x = 1440
